DAVENPORT AND JAMES PORTER, OF SOUTH JACKSONVILLE, FLORIDA RAILWAY-CAR-TRUCK SIDE FRAME Application filed September 26, 1927, Serial No. 222,090. Renewed November 4, 1929.

This invention relates to side frames for railway car trucks, and is more particularly concerned with the construction and arrangement of the journal boxes positioned at the ends of the side frames.

One of the problems concerned in the con struction and arrangement of such side frames has been a construction of journal box housing and support which will facilitate the bodily removal of wheels and axles with their ournal boxes without weakening the box housing and supporting structure, and without involving the use of numerous removable parts subject to corrosion, rust, wear and loose connection, and requiring a substantial outlay in time for their insertion and removal even when not frozen on through rust.

As previously practised or proposed, the housings for the end journal boxes of the side frames have been formed as sections or in separable portions involving the application and removal of heavy bolts to assemble orclose, or to disassemble or open their housings. Such constructions, also, have not been such as to make it possible to ack up the side frame and car body to relieve the weight on the wheels and axles, and permit their re moval except through the use of heavy jack equipment not always available. The ordinary journal jack, which is part of the repair equipment of most trains, is not sufficiently powerful to lift the frame and car the necessary height.

An object of the present invention is to provide in combination with such car side frames, a construction and arrangement of journal box housing which dispenses with the use of the numerous heavy bolts and pins previously used; which is practical and relatively inexpensive to manufacture; which does not sacrifice supporting strength for convenience in operation, but, if anything, increases it; and which will greatly facilitate the removal of the car wheels and axles with their boxes and enable this to be effected through the use of the ordinary journal jack equipment.

It should be stated that in the removal of the wheel axles and their boxes from the ends a of the side frames as previously constructed or proposed, and as proposed herein, jacks are placed under the side frames adjacent to the journal and are operated to engage the frames sufficiently to take the supporting strain off the wheels and axles, whereupon the journal box housings are disassembled or unjointed, and the wheels and axles bodily removed therefrom lengthwise of the car and side frame.

In the accompanying drawings forming part hereof, the invention is illustrated in connection with a truck side frame such as used in standard and ordinary rolling stock, the frame in the preferable embodiment of the invention illustrated, being a drop frame with central bolster and bolster springs and triangular side webbing. Provided at their upper ends are offset under-slung right angular plates bracing the webbing and forming .one side of the housing for the end journal boxes, as well as an abutment for the journal jack, this structural feature constituting part of the present invention as will be later apparent.

Reference is had to the accompanying drawings illustrating a preferable embodiment of this invention in connection with a side frame of this character, in which draw- 1ngs:

Figure 1 is a side elevation of a side frame mounting wheels and axle bosses housed and supported in end housing boxes constructed in accordance with the present invention.

not weakened by hinging a section of the axle box housing, and that the construction provided adequately braces and absorbs transmitted strain.

The half section of the axle box housing provided by the integral hinged side and bottom 14, 15 when unlatched, is dropped upon the hinge pin 19 to clear entirely, the axle box 38 so that the latter, with its axle and wheels may be rolled on the track, or, if broken, pulled laterally from beneath the shelf 12. Before this is attempted, however, a journal box jack, as shown at 89, Figure 2, is placed beneath one of the plates 8 and is raised to engage the plate and take the supporting strain normally received by the side frame from the wheel axle and its box 38, so that the latter may be freely moved away. The point 19, is not only below the bottom line of the area occupied by the axle box 38, but is offset therefrom so that absolute clearance between the axle box and the hinged depending section 14, 15 of its housing is provided. This enables the jack 39 to move the top plate 12 of the housing slightly upwardly so that there is no interference with the withdrawal of the axle and its box either from above or below.

The described construction while representing a preferable embodiment of the invention, is intended to be illustrative rather than restrictive, and it is anticipated thatthe specific form of the invention may be varied within the spiritof the invention as defined by the appended claims.
